Answer 7

3. Find the area of ΔUVW if the area of ΔRST is 36 cm2 and the scale factor is 5/2.

http://tinypic.com/r/1zf6fzp/8

225 cm2

90 cm2

14.4 cm2

2.4 cm2

Answer 8

(5/2) * 36 = 90

Answer 9

That makes sense

Answer 10

4. Find the area of rectangle QRST if the area of rectangle DEFG is 108 cm2 and the scale factor is 3/4.

http://tinypic.com/r/2mwxixk/8

61 cm2

144 cm2

81 cm2

192 cm2

Answer 11

if the linear scale is 3/4 the area scale will be (3/4)^2 = 9/16

If DEFG = 108
QRST = DEFG *16/9 = 108*16/9 = 12*16
Area QRST = 192 cm^2

Answer 12

One more!

Answer 13

Find WZ if the area of trapezoid ABCD is 225 cm2, the area of trapezoid WXYZ is 81 cm2, and AD is 35 cm.

http://tinypic.com/r/dr5n39/8

21 cm

12.6 cm

58.3 cm

97.2 cm

Answer 14

Since both trapezoids are similar and the Area ratio is 225/81
the side ratio will be √ (225/81) = 15/9 = 5/3

So if AD = 35 WZ = 35 *3/5
AD = 21 cms
